ULTRAVIOLET CURABLE URETHANE ACRYLATE COMPOSITION, THIN FILM MOLDED BODY, OPTICAL FILM AND METHOD FOR MANUFACTURING THIN FILM MOLDED BODY |
摘要 |
The present invention is ultraviolet curable without comprising a photoinitiator and exhibits excellent self-healing property, yellowing resistance, transparency and adequate flexibility. An ultraviolet curable urethane acrylate composition which comprises an urethane acrylate oligomer (E) having a (meth)acryloyl group at the molecular terminals which is obtained by the addition reaction of a (meth)acrylic compound (D) having a hydroxyl group with respect to an urethane prepolymer (C) having an NCO group at the molecular terminals which is obtained by reacting a polyol (A) without an aromatic backbone and a polyisocyanate (B) without an aromatic backbone. This composition further comprises 0.2 to 80 parts by mass of an organic solvent (F) without a specific aromatic backbone and does not comprise a photoinitiator. The (meth)acrylic equivalent of (E) is 450 to 1100 g/equivalent and a tanδ peak temperature measured by dynamic viscoelasticity analysis in accordance with JIS K 0129 using a 100 μm thick film produced with the composition is -8 to 45°C. |
