Title:

WATER-BASED POLYURETHANE RESIN COMPOSITION AND ADHESIVE

Document Type and Number:

Japanese Patent JPH09302220

Kind Code:

A

Abstract:

To provide a one-pack water-based polyurethane resin adhesive which, without being heated or otherwise treated during bonding, gives an adhesive film having excellent high-temperature adhesiveness.

A polyester polyol obtained from a carboxylic acid ingredient and a glycol ingredient is reacted with an isocyanate compound and a chain extender comprising a 6-20C compound having a 2-10C side chain and an active- hydrogen group to obtain a polyurethane resin having hydrophilic groups, which is dispersed in an aqueous medium.
