<p>PROBLEM TO BE SOLVED: To obtain a methacrylic resin form with high solvent resistance and almost free from coloring at the time of fabrication by forming a thin layer of stereocomplex methacrylic resin on, at least, one of the faces of the methacrylic resin form. SOLUTION: A stereocomplex methacrylic resin layer with a thickness of 1-500μm is formed on, at least, one of the faces of a methacrylic resin form to obtain a methacrylic resin laminate. If the thickness of the stereocomplex methacrylic resin is 1μm or less, the solvent resistance of the methacrylic resin form is low, and this is not desirable. On the other hand, if the thickness is 500μm or more, the solvent resistance of the surface remains unchanged and besides, the consumption of the stereocomplex methacrylic resin is increased and this is not desirable from the economical point of view. An isotactic methacrylic resin and a syndiotactic methacrylic resin are, for example, in the ratio of (1:99)-(99:1), preferably, (1:9)-(9:1) and further preferably, (1:5)-(5:1).</p> |
