Abstract: The present invention relates to a resin fine particle dispersion optimal for manufacturing a sheet product such as paper. Specifically, an object of the present invention is to provide a resin fine particle dispersion with which a sheet product having excellent heat resistance and high mechanical strength is obtained, and which has a small environmental load due to a small amount of resin particles remaining in wastewater after papermaking. Provided are a resin fine particle dispersion including resin fine particles (A), a fiber material (B), an ionic polyacrylamide (C), and water as essential components, and a sheet product and a friction plate using this.

Abstract: Disclosed are a phenolic hydroxyl group-containing resin which has excellent alkali developing properties and makes it possible to exhibit high heat resistance in a cured product obtained therefrom, a production method therefor, a photosensitive composition, a resist material, a coating film, a curable composition and a cured product thereof, and a resist underlayer film. A phenolic hydroxyl group-containing resin, including a compound (A) having a molecular structure represented by the following Structural Formula (1). (In the formula, R1 represents an alkyl group, an alkoxy group, or an aryl group, R2 represents a hydrogen atom, an alkyl group, or an aryl group, m is an integer of 1 to 3, and n is an integer of 2 to 15. In the case where m is 2 or more, plural R1's may be the same as or different from each other.

Abstract: In order to provide a curing agent (alkoxylated resole-type phenolic resin) with which a coating film having high hot-water resistance, high workability, and high adhesion to metals may be formed without limiting the main agent to be a bisphenol-A-type epoxy resin, the present invention provides a method for producing an alkoxylated resole-type phenolic resin. The method includes reacting a phenol (a1) including meta-cresol with an aldehyde (a2) in the presence of a basic compound to prepare a resole-type phenolic resin (A); and reacting the resole-type phenolic resin (A) with an alcohol (B) in the presence of an acidic compound having an acid dissociation constant (pKa) of 0 or less.
