Filed:

Jun 12, 2009
Appl. No.:

12/746716
Inventors:

Robert J. Sheerin - North Caldwell NJ, US
Jean F. Mauck - Hackettstown NJ, US
Hrire Gharapetian - Ridgewood NJ, US
Gordon Kotora - Oakland NJ, US
Assignee:

Columbia Insurance Company - Omaha NE
International Classification:

C08K 3/32
C08K 5/10
C08K 5/45
C08L 31/00
US Classification:

523122, 524 84, 524317, 524417, 524556
Abstract:

The present invention relates to an aqueous coating composition comprising a treated latex polymer dispersion with less than about 50 ppm of unreacted monomers. The latex polymer dispersion can be treated by various means, including stripping and chasing, to remove unreacted monomers from the dispersion. Unreacted monomers significantly contribute to paint odor. In an innovative aspect of the present invention, the synergistic combination of the treated latex dispersion with pigments and other low or zero-VOC additives results in an aqueous coating composition with de minimis levels of volatile emissions, low odor, and paint performance comparable to premium latex paints.

US Patent:

62762737, Aug 21, 2001
Filed:

Jun 11, 1999
Appl. No.:

9/330072
Inventors:

Patrice M. Aurenty - Wood-Ridge NJ
Roshanak Debeaud - Cranford NJ
Edward Stone - Morris Plains NJ
Gordon Kotora - Clifton NJ
Assignee:

Kodak Polychrome Graphics LLC - Norwalk CT
International Classification:

B41N 303
B41N 308
US Classification:

101457
Abstract:

A printing plate precursor for direct receipt of an image-wise applied ink receptive layer the precursor having a desorbable surfactant adsorbed on at least one surface in an amount effective to improve the resolution of the subsequently image-wise applied ink receptive layer. The printing plate precursor can be used to prepare a printing plate having improved resolution. The printing plate may be prepared by (a) applying a desorbable surfactant to at least one surface of a printing plate substrate, (b) removing non-adsorbed surfactant from the surface, (c) applying a fluid composition containing an ink receptive material onto at least a portion of the surface in the form of a desired image, thereby providing an ink receptive image layer; and (d) removing the desorbable surfactant from any area of the surface which does not form part of the desired image.
