Abstract
The present invention provides a transparent laminate comprising a laminate substrate obtained by bonding a Second substrate composed of a polycarbonate-based resin to a first surface of a first substrate composed of an acrylic resin via a first bonding layer composed of a resin having a glass transition temperature(Tg) of about 50° C. or less, and a surface layer composed of a polycarbonate-based resin bonded via a surface bonding layer composed of an acrylic resin to a second surface of the first substrate, which laminate is light and excellent in transparency and excellent in impact resistance when it repeatedly receives an impact.
Claims8
A transparent laminate comprising:
- a laminate substrate obtained by bonding a second substrate composed of a polycarbonate resin to a first surface of a first substrate composed of an acrylic resin via a first bonding layer composed of a resin having a glass transition temperature (Tg) of 50° C. or less;
- and a surface layer composed of a polycarbonate resin bonded via a surface bonding layer composed of an acrylic resin to a second surface of said first substrate;
- wherein the thickness of said surface layer is from about 0.1 to about 3 mm;
- wherein the thickness of said first substrate is from about 3 to about 30 mm and the thickness of said second substrate is from about 3 to about 15 mm;
- and
- wherein the thickness of said first bonding layer is from about 0.1 to about 4 mm and the thickness of said surface bonding layer is from about 20 to about 200 μm.
