Abstract
A polymer complex is disclosed which is the reaction product of one or more polymers having a terminal or pendant hydroxyl group, or a terminal or pendent carboxyl group, or combinations thereof, with at least one metal complex and one alkyl phosphate. This polymer complex acts as an adhesion promotion agent as well as a viscosity stabilizer when formulated in a printing ink or coating.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A polymer complex comprising the reaction product of:
one or more polyurethanes having:
a) a terminal or pendent carboxyl group; or
b) a combination of a terminal or pendent carboxyl group and a terminal or pendent hydroxyl group;
with at least one metal orthoester and at least one alkyl phosphate.
2 . The polymer complex of claim 1 , wherein said metal orthoester has the formula metal (OR) 4 , wherein each of the four R groups is independently an alkyl group.
3 . The polymer complex of claim 2 , wherein said alkyl group is a C 1 to C 8 alkyl group.
4 . The polymer complex of claim 2 , wherein said alkyl group is a C 3 to C 4 alkyl group.
5 . The polymer complex of claim 1 , wherein said metal orthoester is tetraisopropyltitanate.
6 . The polymer complex of claim 1 , wherein said alkyl phosphate is a monoalkyl phosphate having the formula R 1 PO(OH) 2 or a dialkylphosphate having the formula (R 2 O)(R 3 O)PO(OH), wherein each of R 1 , R 2 and R 3 is independently an alkyl.
7 . The polymer complex of claim 6 , wherein said alkyl group is a C 1 to C 10 alkyl group.
8 . The polymer complex of claim 6 , wherein said alkyl group is a C 1 to C 5 alkyl group.
9 . The polymer complex of claim 1 , wherein said alkyl phosphate is amyl acid phosphate.
10 . An ink or coating composition containing an adhesion promoting agent comprising the reaction product of:
one or more polyurethanes having
a) a terminal or pendent carboxyl group; or
b) a combination of a terminal or pendent carboxyl group and a terminal or pendent hydroxyl group;
with at least one metal orthoester and at least one alkyl phosphate.
11 . The composition of claim 10 , wherein said metal orthoester has the formula metal (OR) 4 , wherein each of the four R groups is independently an alkyl group.
12 . The composition of claim 11 , wherein said alkyl group is a C 1 to C 8 alkyl group.
13 . The composition of claim 11 , wherein said alkyl group is a C 3 to C 4 alkyl group.
14 . The composition of claim 10 , wherein said metal orthoester is tetraisopropyltitanate.
15 . The composition of claim 10 , wherein said alkyl phosphate is a monoalkyl phosphate having the formula R 1 PO(OH) 2 or a dialkylphosphate having the formula (R 2 O)(R 3 O)PO(OH), wherein each of R 1 , R 2 and R 3 is independently an alkyl.
16 . The composition of claim 15 , wherein said alkyl group is a C 1 to C 10 alkyl group.
17 . The composition of claim 15 , wherein said alkyl group is a C 1 to C 5 alkyl group.
18 . The composition of claim 26 , wherein said alkyl phosphate is amyl acid phosphate.
19 . A method of improving the adhesion performance of an ink or coating composition comprising adding to said composition an agent comprising the reaction product of one or more polyurethanes having a terminal or pendent carboxyl group or a combination of a terminal or pendent carboxyl group and a terminal or pendent hydroxyl group, and at least one metal orthoester and at least one alkyl phosphate.
20 . The method of claim 19 wherein the viscosity stability of an ink or coating composition is also enhanced.
21 . The method of claim 19 , wherein said metal orthoester has the formula metal (OR) 4 , wherein each of the four R groups is independently an alkyl group.
22 . The method of claim 21 , wherein said alkyl group is a C 1 to C 8 alkyl group.
23 . The method of claim 21 , wherein said alkyl group is a C 3 to C 4 alkyl group.
24 . The method of claim 19 , wherein said metal orthoester is tetraisopropyltitanate.
25 . The method of claim 19 , wherein said alkyl phosphate is a monoalkyl phosphate having the formula R 1 PO(OH) 2 or a dialkylphosphate having the formula (R 2 O)(R 3 O)PO(OH), wherein each of R 1 , R 2 and R 3 is independently an alkyl.
26 . The method of claim 25 , wherein said alkyl group is a C 1 to C 10 alkyl group.
27 . The method of claim 25 , wherein said alkyl group is a C 1 to C 5 alkyl group.
28 . The method of claim 19 , wherein said alkyl phosphate is amyl acid phosphate.
29 . The method of claim 19 which also promotes stabilizing the viscosity of the ink or coating composition.
30 . The method of claim 29 , wherein said metal orthoester has the formula metal (OR) 4 , wherein each of the four R groups is independently an alkyl group.
31 . The method of claim 30 , wherein said alkyl group is a C 1 to C 8 alkyl group.
32 . The method of claim 30 , wherein said alkyl group is a C 3 to C 4 alkyl group.
33 . The method of claim 29 , wherein said metal orthoester is tetraisopropyltitanate.
34 . The method of claim 29 , wherein said alkyl phosphate is a monoalkyl phosphate having the formula R 1 PO(OH) 2 or a dialkylphosphate having the formula (R 2 O)(R 3 O)PO(OH), wherein each of R 1 , R 2 and R 3 is independently an alkyl.
35 . The method of claim 34 , wherein said alkyl group is a C 1 to C 10 alkyl group.
36 . The method of claim 34 , wherein said alkyl group is a C 1 to C 5 alkyl group.
37 . The method of claim 29 , wherein said alkyl phosphate is amyl acid phosphate.Cited by (0)
