Title:
URETHANE (METH)ACRYLATE OLIGOMER AND SHEET USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/016146
Kind Code:
A1
Abstract:
Disclosed is a urethane (meth)acrylate oligomer which is obtained by reacting at least one polyoxyalkylene polyol (A), at least one monool (B1) soluble in the component (A) and/or at least one silane coupling agent (B2) reactive with an isocyanate group, at least one polyisocyanate (C) and at least one hydroxylated mono(meth)acrylate compound (D) at a ratio at which the equivalent weights of hydroxy groups, active hydrogen groups and isocyanate groups in the respective components satisfy the following formulae (1)-(3). The urethane (meth)acrylate oligomer does not substantially contain an unreacted isocyanate group. B(active hydrogen) + D(OH) = C(NCO) - A(OH) (1) 1.05 ≤ C(NCO)/A(OH) ≤ 2 (2) {C(NCO) - 2A(OH) + 2m} × 0.35 ≤ D(OH) ≤ {C(NCO) - 2A(OH) + 2m} × 0.70 (3) In the formulae (1)-(3), A(OH) represents the total equivalent weight of hydroxy groups contained in the component (A); B(active hydrogen) represents the total equivalent weight of active hydrogen groups contained in the component (B1) and/or the component (B2); C(NCO) represents the total equivalent weight of isocyanate groups contained in the component (C); D(OH) represents the total equivalent weight of hydroxy groups contained in the component (D); and m represents the number of moles of the component (A).
