Method used

[0050] In the present invention, those having a basic N atom in the structural formula of the pigment can be used particularly preferably. Pigments having these basic nitrogen atoms exhibit good dispersibility in the photocurable composition of the present invention. The reason for this is not fully elucidated, but it is presumed to be the result of a favorable effect on the affinity between the photopolymerizable compound and the pigment.

[0109] As the acrylic copolymer of the alkali-soluble resin of the present invention, a hydrophobic group can be introduced by copolymerizing at least one of the acrylic monomers containing the following hydrophobic groups. By having these hydrophobic groups in the side chain, it is possible to control the infiltration of the developing solution into the film at the time of development in the case of film formation, so that the development speed can be appropriately controlled. In addition, there is no chemical coloring over time, and even when a colorant having colors such as red, green, or blue is used, deterioration over ti...

Abstract

In a photo curable composition including colorant, alkali-soluble resin, polymerize compound, initiators for photopolymerization and solvent, the average grain diameter of the colorant is smaller than 150 nm, the alkali-soluble resin and/or polymerize compound have alkylene oxide chains. The solvent kind with boiling point above 200 DEG C and the solvent kind with boiling point below 200 DEG C are respectively including at least one solvent. The total sum (Sigma T multiplies X) of the product (T multiplies X) of the boiling points T (DEG C) between the solvent kinds and the content X (mass%) relative to the solvent total amount is 120x10<2>-190x10<2> (DEG C%).
