ISOCYANATE COMPOSITION, MICROCAPSULE AND ITS MANUFACTURING METHOD, RECORDING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a heat-sensitive recording material which is useful as a wall material of a microcapsule having a high heat-sensitivity and a high coloring density, and comprises an isocyanate composition being excellent in raw preserving property and the microcapsule, and also, has a high sensitivity and is excellent in color productivity and raw preserving property, and to provide its manufacturing method.

SOLUTION: This isocyanate composition contains an additive of a polymer (A) and a multi-functional isocyante (B). The polymer (A) is radical polymerized with the existence of a chain transfer agent containing an active hydrogen by using a vinyl monomer containing at least a polymerizable compound having a polyether represented by the general formula (I). The multi-functinal isocyanate (B) has two or more isocyanate radicals in the molecule.
