1. A method for manufacturing a pigment dispersed liquid for use in forming a light curable composition, the method consisting essentially of the following steps:
- (a) providing a polymerizable compound of N-vinylformamide or ethyleneglycol monoallyletlher;
(b) preparing a mixture by mixing, a pigment;
a polyoxyalkylene polyalkylene amine of formula (C2H4N)—
(PO)x(EO)y—
OH, wherein n, x and y are each at least one;
a polymerization inhibitor which is p-methoxyphenol; and
the polymerizable compound of N-vinylformamide or ethyleneglycol monoallylether, and(c) dispersing the mixture to form the pigment dispersed liquid, wherein the polymerization inhibitor is present in the pigment dispersed liquid in an amount less than 0.01 wt %.
