Title:
ENERGY RAY-CURABLE RESIN COMPOSITION AND WEATHER-RESISTANT HARD COAT FILM UTILIZING SAME
Document Type and Number:
WIPO Patent Application WO/2014/003139
Kind Code:
A1
Abstract:
Provided are: an energy ray-curable resin composition which forms a coating film that has excellent coating film hardness, scratch resistance, weather resistance and moisture resistance when cured; and a weather-resistant hard coat film which utilizes this energy ray-curable resin composition.
An energy ray-curable resin composition which contains (A) an energy ray-curable oligomer, (B) at least one ultraviolet absorbent that is selected from among benzotriazole ultraviolet absorbents and triazine ultraviolet absorbents, (C) a hindered amine light stabilizer and (D) a photopolymerization initiator. The component (B) is added in an amount of 2-12 parts by mass per 100 parts by mass of the component (A). The component (D) contains (D1) at least one photopolymerization initiator that has a maximum absorbance of 0.1 or more within the wavelength range of 340-400 nm in a 0.01% by mass solution which is obtained by dissolving the photopolymerization initiator in methanol or acetonitrile, and (D2) at least one photopolymerization initiator that has a maximum absorbance of 0.1 or more within the wavelength range of 220-280 nm in a 0.001% by mass solution which is obtained by dissolving the photopolymerization initiator in methanol or acetonitrile.
