Title:
SAFETY GLASS
Document Type and Number:
Japanese Patent JPH06134930
Kind Code:
A
Abstract:
PURPOSE: To provide safety glass having durability more excellent than that of conventional safety glass having function controlling light transmissivity.
CONSTITUTION: Safety glass is obtained by laminating a glass plate 1, a bonding material, a plastic film 3 having a selective light transmitting film 2 laminated on at least one surface thereof, a plastic film protecting layer 5 having a heat shrinkage factor of 1% or more and characterized by that the ratio (MD/TD) of the heat shrinkage factor in the traverse direction(TD) crossing the machine direction(MD) of the film 3 at a right angle is 0.7-1.4, an bonding material 4 and a glass plate 1 in this order.
