Title:
PRODUCTION OF DOUBLE-SIDE LENTICULAR LENS SHEET
Document Type and Number:
Japanese Patent JP3230915
Kind Code:
B2
Abstract:
PURPOSE: To produce a double-side lenticular lens sheet having the lenticular lens patterns of lens molds accurately transferred thereto, having lens layers uniform in thickness formed thereto and having excellent optical characteristics free from axial shift with good productivity.
CONSTITUTION: A first active energy beam curable resin layer 3 is irradiated with active energy beam in a state deformed along the lenticular lens patterns of lens molds 7, 7' to be cured and shaped to form a first lenticular lens. Thereafter, a second active energy beam curable resin layer 9 is interposed between the surface opposite to the surface having the first lenticular lens formed thereto of a sheet like transparent base material 1 and the lens mold having a lenticular lens pattern formed thereto and irradiated with active energy beam to be cured and shaped to form a second lenticular lens.
