Abstract:
1. An inorganic fine particle dispersion liquid comprising: inorganic fine particles; and an inorganic fine particle dispersant, comprising, as an essential component, a compound resin (A) obtained by forming a bond between a polysiloxane segment (a1) and a vinyl-based polymer segment (a2), wherein the polysiloxane segment (a1) has a structural unit represented by general formula (1) and/or general formula (2), the polysiloxane segment (a1) further has a first silanol group and/or a first hydrolyzable silyl group before forming the bond, wherein the vinyl-based polymer segment (a2) has a second silanol group and/or second hydrolyzable silyl group before forming the bond, wherein the bond is represented by general formula (3), the bond being formed as a result of a dehydration condensation reaction between the first silanol group and/or first hydrolyzable silyl group and the second silanol group and/or the second hydrolyzable silyl group: (in general formulae (1) and (2), R 1 , R 2 , and R 3 each independently represent a group having one polymerizable double bond selected from the group consisting of —R 4 —CH═CH 2 , —R 4 —C(CH 3 )═CH 2 , —R 4 —O—CO—C(CH 3 )═CH 2 , and —R 4 —O—CO—CH═CH 2 (where R 4 represents a single bond or an alkylene group having 1 to 6 carbon atoms), an alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 3 to 8 carbon atoms, an aryl group, or an aralkyl group having 7 to 12 carbon atoms;) (in general formula (3), the carbon atom is part of the vinyl-based polymer segment (a2) and the silicon atom bonded only to the oxygen atom is part of the polysiloxane segment (a1)).
