A resin composition including (A) a glycidyloxy group-containing organopolysiloxane in an amount of 100 parts by weight, (B) a neutral salt in an amount of 0.001 parts by weight or more and 1 part by weight or less, (C) a β-dicarbonyl compound in an amount of 0.5 parts by weight or more and 10 parts by weight or less, and (D) a solvent in an amount of 20 parts by weight or more and 300 parts by weight or less is provided. In a multi-liquid curable resin composition including a first liquid and a second liquid, the first liquid is the resin composition, and the second liquid contains (E) an organoaluminum compound and/or organotitanium compound.

Resin composition, method for producing same, and multi-liquid curable resin composition

A resin composition containing (A) an organopolysiloxane having a glycidyloxy group, and (B) at least one selected from the group consisting of a triarylalkoxysilane, a diaryldialkoxysilane, a hydrolysate thereof and a partially hydrolyzed/condensed product thereof is provided. The resin composition may further contain (C) a β-dicarbonyl compound. The resin composition may further contain (D) an organic compound having one or more of an epoxy group, an oxetanyl group and a vinyl ether group. The resin composition may be mixed with (E) an organoaluminum compound and/or organotitanium compound and be cured.

A curable composition includes a condensation product having a weight average molecular weight of 30,000 or less and a curing agent, the condensation product being obtained by hydrolysis and condensation of a first and second silane compound in the presence of a neutral salt catalyst. The condensation product also has a ratio Y/X of 0.2 or less, wherein X is the number of moles of an ORgroup directly bonded to silicon atoms of the first and second silane compounds, and Y is the number of moles of an ORgroup directly bonded to a silicon atom of the condensation product. The first silane compound is represented by R&#x2014;(SiR(OR)), and the second silane compound is represented by R&#x2014;(SiR(OR)).

Photocurable and thermosetting resin composition, cured product, and laminate

An active energy ray-curable composition includes (A) a condensate having a weight average molecular weight of 20,000 or less, and (B) a photoacid generator, with the condensate (A) being obtained by hydrolysis/condensation of: (I) a silane compound containing a hydrolyzable silyl group represented by formula (I): R&#x2014;(SiR(OR). A ratio (Y/X) of Y to X is 0.2 or less, where X represents the number of moles of ORgroups directly bonded to silicon atoms in the silane compound (I) which is a starting material of the condensate (A) and Y represents the number of moles of ORgroups directly bonded to silicon atoms in the condensate (A).

Active energy ray-curable composition

A method for producing a siloxane resin, by hydrolyzing and condensing a silane compound containing a hydrolyzable silyl group represented by RSiXusing a neutral salt as a catalyst. In the formula RSiX, R represents an organic group having a carbon atom directly bonded to Si, X represents a hydroxyl group or a hydrolyzable group, and n represents an integer of 0 to 3, provided that when n is 2 or greater each R may be the same as or different from each other, and when (4-n) is 2 or greater, each X may be the same as or different from each other.
