<p><P>PROBLEM TO BE SOLVED: To provide a thermoplastic resin sheet usable as the interlayer of a glass laminate having superior resisting performance to penetration ranging over from a low-temperature region to a high-temperature region. <P>SOLUTION: In the thermoplastic resin sheet, a first polyvinyl acetal resin layer A is laminated on both sides of a second polyvinyl acetal resin layer B under the condition that the first polyvinyl acetal resin layer A is made mainly of an acetalized matter of polyvinyl alcohol consisting of 4-6C aldehyde and the second polyvinyl acetal resin layer B is made mainly of a co-acetalized matter of polyvinyl alcohol consisting of 1-3C aldehyde and the degree of acetalization of the second polyvinyl acetal resin layer B is≥55 mol%. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
