17 . A process for increasing the matting effect of a paint or ink comprising adding the precipitated silica as claimed in claim 13 as a matting agent to said paint.
18 . A paint or ink, which includes the precipitated silica as claimed in claim 13 as a matting agent.
19 . A process for increasing the matting effect of a paint or ink comprising adding the precipitated silica as claimed in claim 14 as a matting agent to said paint.
20 . A paint or ink, which includes the precipitated silica as claimed in claim 14 as a matting agent.
21 . A process for increasing the matting effect of a paint or ink comprising adding the precipitated silica as claimed in claim 15 as a matting agent to said paint.
22 . A paint or ink, which includes the precipitated silica as claimed in claim 15 as a matting agent.
23 . A process for increasing the matting effect of a paint or ink comprising adding the precipitated silica as claimed in claim 16 as a matting agent to said paint.
24 . A paint or ink, which includes the precipitated silica as claimed in claim 16 as a matting agent.Join the waitlist — get patent alerts
