Title:
METHOD FOR RECYCLING OPTICAL DEVICE CONSTITUENT MEMBERS AND METHOD FOR EVALUATING REWORKABILITY OF OPTICAL DEVICE CONSTITUENT LAMINATE
Document Type and Number:
WIPO Patent Application WO/2016/002763
Kind Code:
A1
Abstract:
Proposed is a new method for separating two optical device constituent members from an optical device constituent laminate formed by temporarily bonding the two optical device constituent members via a transparent adhesive material, and recycling the optical device constituent members. The present invention is a method for recycling optical device constituent members. The method uses, as a recycle starting material, an optical device constituent laminate (4) configured by bonding two optical device constituent members via a transparent adhesive material (1) in an uncross-linked state, the transparent adhesive material being softened by heating and cross-linked by light irradiation, and is provided with a step for dividing the transparent adhesive material by heating at least the transparent adhesive material of the optical device constituent laminate, erecting the optical device constituent laminate, hanging a linear member (5) along the end edge of the transparent adhesive material located at the upper end edge (4a) of the optical device constituent laminate, and applying a load by the linear member, and producing two optical device constituent members to each of which a divided one-side transparent adhesive material adheres.
