Abstract:
1. A curable composition comprising: (A) a polymerizable compound having an alkyleneoxy group having two or more carbon atoms represented by the following formula (i) and formula (ii): wherein each E independently represents —((CH each X independently represents an acryloyl group, a methacryloyl group, a hydrogen atom or a carboxyl group; the sum of acryloyl groups and methacryloyl groups in formula (i) is 3 or 4; and each m independently represents an integer from 0 to 10, while the sum of the respective m's is an integer from 1 to 40; the sum of acryloyl groups and methacryloyl groups in formula (ii) is 5 or 6; and each n independently represents an integer from 0 to 10, while the sum of the respective n's is an integer from 1 to 60; (B) a polymerizable compound lacking an alkyleneoxy group having two or more carbon atoms represented by the following formula (iii) or formula (iv): wherein each Z independently represents an acryloyl group, a methacryloyl group, a hydrogen atom or a carboxyl group; the sum of acryloyl groups and methacryloyl groups in formula (iii) is 3 or 4; and the sum of acryloyl groups and methacryloyl groups in formula (iv) is 5 or 6; (C) an i-line absorber represented by the following formula (1): wherein R (D) a photopolymerization initiator; (F) an alkali-soluble resin; and (F) a pigment, wherein the mass ratio [(A)/((A)+(B))] is from 0.6 to 0.9, and the i-line transmittance obtained in a case in which the curable composition is formed into a coating film having a thickness of 0.7 μm, is 10% or less.
