Title:
PRODUCTION OF LAMINATED GLASS
Document Type and Number:
Japanese Patent JPH06305785
Kind Code:
A
Abstract:

PURPOSE: To produce the laminated glass which does not generate striae even at the time of using a thick interlayer of the laminated glass and has excellent physical properties by using a specific photosetting composition as the adhesive and irradiating the composition with ultraviolet rays under specific conditions to harden it.

CONSTITUTION: A photosetting composition consisting essentially of (a), (b) and (c) described below is used as the adhesive. As for the hardening conditions, the first irradiation by ultraviolet rays of a 10 to 1000mW/cm2 light intensity at 360nm wavelength and a 1000 to 5000mJ/cm2 integrated light quantity and, if necessary, the second irradiation by ultraviolet rays of a 0.1 to 10mW/cm2 light intensity at 360nm wavelength are performed so that the total integrated light quantity of the first and second irradiation is at least 3000mJ/cm2. (a) is e.g. a radicallypolymerizable compound represented by the formula, wherein each of R1, R2 and R3 is a hydrogen atom or a methyl group; R4 is a C1 to C12 alkyl group, etc.; (l) and (m) are 0 or ≥1 integers excluding the case of l=m=0. (b) is a non-radically-polymerizable compound such as polyalkylene glycol, etc., (c) is a photopolymerization initiator.
