Meltable ink composition

Abstract

A meltable ink composition, which is solid at room temperature and liquid at elevated temperature, which ink composition is suitable for use in an inkjet printer, the ink composition being provided with a resin which contains a compound which is the reaction product of a di-alkanolamine and a monofunctional aromatic acid and optionally a difunctional acid.

1 . An ink composition containing a vehicle composition and optional additives, which ink composition is solid at room temperature and liquid at elevated temperature, said ink composition being suitable for use in an inkjet printer, the vehicle composition comprising a resin, wherein the resin contains a compound which is the reaction product of a di-alkanolamine and a mono-functional aromatic acid.  
   
   
       2 . The ink composition according to  claim 1 , wherein the compound is the reaction product of di-isopropanolamine and benzoic acid, the benzoic acid being optionally substituted with an alkyl and/or alkoxy group.  
   
   
       3 . The ink composition according to  claim 2 , wherein the benzoic acid is substituted with a C1-C4 alkyl and/or a C1-C4 alkoxy group.  
   
   
       4 . The ink composition according to  claim 1 , wherein the ink composition is also provided with a meltable crystalline material.  
   
   
       5 . The ink composition of  claim 4 , wherein the ink composition is further provided with an amorphously solidifying monomer.  
   
   
       6 . The ink composition according to  claim 4 , wherein the ink composition is also provided with a viscosity controlling agent.  
   
   
       7 . The ink composition of  claim 6 , wherein the viscosity controlling agent is a gelling agent.
