Abstract
Official abstract text for this publication.
Provided are a solvent-free two-component type adhesive capable of guaranteeing a practical packaging property, with an excellent curing property and significantly shortening aging time, a laminated film using the same, and a polyol composition for an adhesive. An adhesive, characterized in comprising a polyisocyanate composition (X) containing a polyisocyanate (A), and a polyol composition (Y) containing a polyol (C) and a tertiary amine compound (B) having multiple hydroxyl groups, as necessary components.
First claim
Opening claim text (preview).
The invention claimed is: 1. An adhesive comprising: a polyisocyanate composition (X), containing: a polyisocyanate (A), and a polyester composition (Y), containing: a polyol (C) selected from the group consisting of a polyester polyol, a polyester urethane polyol, a polyether urethane polyol, a polyether polyol and a castor oil-based polyol, and a tertiary amine compound (B) having multiple hydroxyl groups, the adhesive having a viscosity of 2500 mPa·s or less when applied to a base material. 2. The adhesive according to claim 1 , wherein an amine value of the adhesive ranges from 0.5 to 40 mgKOH/g. 3. The adhesive according to claim 1 , wherein the polyol composition (Y) has a mass ratio of from 10 to 150 when the polyisocyanate composition (X) is set as 100. 4. The adhesive according to claim 1 , further comprising an alicyclic amide compound. 5. The adhesive according to claim 4 , wherein the mixing amount of the alicyclic amide compound is 0.1 to 5 parts by mass per 100 parts by mass of the polyol (C).
