RESIN LAMINATE, BUILDING MEMBER, AND METHOD FOR PRODUCING RESIN LAMINATE
PROBLEM TO BE SOLVED: To provide a resin laminate which suppresses occurrence of poor appearance during or after formation of a hard coat layer, and has transparency, scratch resistance, antifouling properties and weather resistance.SOLUTION: There is provided a resin laminate which is formed by laminating at least three layers of a resin layer A containing a thermoplastic resin composition a as a main component, a resin layer B containing a thermoplastic resin composition b as a main component, and a resin layer C formed from a curable resin composition c in this order, where a storage elastic modulus E'(a) of the thermoplastic resin composition a and a storage elastic modulus E'(b) of the thermoplastic resin composition b, which are measured by a dynamic viscoelasticity tensile method performed according to JIS K 7244 on conditions of a frequency of 10 Hz and a glass transition temperature Tg (b) of the thermoplastic resin composition b of -20°C, satisfy the following relational expression (I): E'(b)>E'(a).SELECTED DRAWING: None
【課題】ハードコート層の形成時または形成後における外観不良の発生が抑制され、透明性、耐擦傷性、防汚性および耐候性を兼ね備えた樹脂積層体を提供する。【解決手段】熱可塑性樹脂組成物ａを主成分とする樹脂層Ａ、熱可塑性樹脂組成物ｂを主成分とする樹脂層Ｂ、および硬化性樹脂組成物ｃから形成される樹脂層Ｃの少なくとも三層をこの順に積層してなる樹脂積層体において、ＪＩＳ Ｋ ７２４４に準拠し、周波数１０Ｈｚ、上記熱可塑性樹脂組成物ｂのガラス転移温度Ｔｇ（ｂ）−２０℃の条件で行われる動的粘弾性引張法により測定される、上記熱可塑性樹脂組成物ａの貯蔵弾性率Ｅ´（ａ）と上記熱可塑性樹脂組成物ｂの貯蔵弾性率Ｅ´（ｂ）とが以下の関係式（Ｉ）を満たす、樹脂積層体とする。Ｅ´（ｂ）＞Ｅ´（ａ） ・・・（Ｉ）【選択図】なし
