Abstract: The present invention provides a material for a molded resin as a material for a semiconductor light-emitting device that can yield a highly durable (light resistance and heat resistance) molded resin and can also improve the LED output through an excellent reflectivity. The present invention also provides an easily moldable material for a molded resin for a semiconductor light-emitting device. The material for a molded resin for a semiconductor light-emitting device is a resin composition, comprising (A) a polyorganosiloxane, (B) a white pigment, and (C) a curing catalyst, wherein the white pigment (B) has the following characteristics (a) and (b): (a) an aspect ratio 1.2 or more and 4.0 or less, and (b) a primary particle diameter 0.1 ?m or more and 2.0 ?m or less.

Abstract: Disclosed is a recording liquid including an aqueous pigment dispersion, which has high dispersion stability and high discharge properties and gives a print with superior gloss. Specifically, the aqueous pigment dispersion contains a pigment; a polymer containing cationic monomer structural units and hydrophobic monomer structural units (hydrophobic-group-containing cationic polymer); and a polymer containing anionic monomer structural units and hydrophobic monomer structural units (hydrophobic-group-containing anionic polymer), in which the ratio of the number of anionic groups in the hydrophobic-group-containing anionic polymer to the number of cationic groups in the hydrophobic-group-containing cationic polymer is 1.0 or more and 8 or less. The molar ratio of the hydrophobic monomer structural units to the anionic monomer structural units in the hydrophobic-group-containing anionic polymer is from 5/95 to 50/50 or the content of the pigment is 51 percent by weight or more based on the solids content.
