ABSTRACT:
The present invention relates to a radiation curable ink formulation which has a tan .delta. of from about 0.5 to about 1.5. The radiation curable ink formulation includes a pigment, a radiation cross-linkable monomer or oligomer, and a rheology modifier. Flat panel color filters which contain a black radiation curable ink formulation and one or more colored radiation curable ink formulations are also disclosed. At least one of the black and colored radiation curable ink formulations has a tan .delta. of from about 0.5 to about 1.5 and includes a pigment, a radiation cross-linkable monomer or oligomer, and a rheology modifier. Methods for manufacturing these flat panel color filters are also disclosed. The radiation curable ink formulations of the present invention have the advantage of permitting clean doctoring. When used with black pigments to produce a raised black matrix surface pattern on a transfer layer, intrusion of the black ink into the areas occupied by colored inks is minimal, thus producing flat panel color filters with reduced haze when compared to previously-known flat panel color filters. Also described is a radiation curable formulation containing a radiation cross-linkable monomer or oligomer; a photoinitiator selected from the group consisting of 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)-butan-1-one, 2,4,6-trimethylbenzoyl diphenyl phosphine oxide, bis(2,4,6-trimethylbenzoyl) phenyl phosphine oxide, and combinations thereof; and chloropropoxythioxanthone. The radiation curable formulation has exceptionally high cure rate.
