| 摘要 |
<p>The invention provides a light-sensitive black composition, containing (a) carbon black, (b) dispersant, (c) pigment derivatives, (d) photo-polymerization initiator, and (e) olefinic-bond unsaturated compound. The carbon black (a) has the average primary particle-size of 15 to 25nm, specific surface area of 100 to 180m<2>/g, and absorption capacity to dibutyl phthalate of less than 55cm<3>/100g. The dispersant (b) is composed of phosphate esters pigment dispersant or specific acidic dispersant. The pigment derivatives (c) are composed of specific alkaline pigment derivatives.</p> |
