A method for manufacturing a color filter in which colorant is imparted on a substrate using an ink jet printing system, comprising the steps of:
- (1) forming on said substrate a resin layer comprising a composition having an ink-accepting property which deteriorates by light exposure optionally followed by heating,
- (2) subjecting the resin layer to a single patterning exposure, optionally followed by heating, in order to deteriorate the ink accepting property of the exposed portions,
- (3) providing the colorant to unexposed portions of the resin layer using said ink jet printing system, to form a pattern of at least two colors, and
- (4) curing the colored portions of the resin layer by light exposure or heating.
A method for manufacturing a color filter in which colorant is imparted on a substrate having light transmittable portions by an ink jet printing system, comprising the steps of:
- (1) forming on said substrate a resin layer comprising a composition which has an ink accepting property and in which an amount of a hydrophilic group decreases by light exposure optionally followed by heating,
- (2) subjecting the resin layer to a single patterning exposure, optionally followed by heating to decrease the amount of said hydrophilic group,
- (3) providing the colorant to unexposed portions of said resin layer using an ink jet printing system, to form a pattern of at least two colors, and
- (4) curing the colored portions of the resin layer by light exposure or heating.
A method for manufacturing a color filter in which colorant is imparted on a substrate having light transmittable portions using an ink jet printing system, comprising the steps of:
- (1) forming on the substrate a resin layer having an ink-accepting property which deteriorates by light exposure, optionally followed by heating, said resin layer comprising:
- (a) homopolymer of a monomer comprising a structural unit represented by formula (I) or a copolymer comprising a structural unit represented by formula (I) and another vinyl monomer:
- ##STR32## wherein R.sub.1 is hydrogen atom or a methyl group;
- and R.sub.2 is a hydrogen atom or an alkyl group having 1 to 5 carbon atoms, and
- (b) a compound selected from the group consisting of halogenated triazine compounds, diphenyliodonium salt derivatives and triphenylsulfonium salt derivatives,
- (2) subjecting the resin layer to a single patterning exposure, optionally followed by heating to deteriorate the ink-accepting property of the exposed portions of the resin layer,
- (3) providing the colorant to unexposed portions of the resin layer using an ink jet printing system, to form a pattern of at least two colors, and
- (4) curing the resin layer by light exposure or heating.
A method for manufacturing a color filter in which colorant is imparted on a substrate having light-transmittable portions by an ink jet printing system, comprising the steps of:
- (1) forming on the substrate a resin layer comprising a composition which can be rendered ink accepting by light exposure,
- (2) subjecting the resin layer to a single patterning exposure, optionally followed by heating to renter the exposed portions of the resin layer ink-accepting,
- (3) providing the colorant to exposed portions of the resin layer using said ink jet printing system, to form a pattern of at least two colors, and
- (4) curing the colored portions of the resin layer by light exposure or heating.
A method for manufacturing a color filter in which colorant is imparted on a substrate having light transmittable portions using an ink jet printing system, comprising the steps of:
- (1) forming on said substrate a resin layer which can be rendered ink-accepting by light exposure, optionally followed by heating, said resin layer comprising:
- (a) a compound selected from the group consisting of halogenated triazine compounds, diphenyliodonium salt derivatives and triphenylsulfonium salt derivatives, and (b) an acrylic resin having a structure unit represented by the following formula (V):
- ##STR33## where R.sub.1 is hydrogen or a C.sub.1-5 alkyl group;
- R.sub.2 is a C.sub.1-5 alkylene group or a phenylene group;
- R.sub.3 is a C.sub.1-5 alkyl group, an alkyl-substituted silyl group, a phenyl group or a substituted aromatic group,
- (2) subjecting the resin layer to a single patterning exposure, optionally followed by heating to render the exposed portions of the resin layer ink-acceptable,
- (3) providing the colorant to the ink-accepting portions of the resin layer using an ink jet printing system, to form a pattern of at least two colors, and
- (4) curing the resin layer by light exposure or heating.
