    • The invention relates to a process for the manufacture of a weather resistant laminate comprising a resin impregnated fibrous layer, preferably a resin impregnated decorative paper layer on a carrier layer. The invention further relates to laminates obtainable with the process according to the invention, to an intermediate laminate for use in the manufacture of the weather resistant laminate and to the use of said laminates. The process comprises the steps of providing a resin impregnated fibrous layer, curing the resin of the resin impregnated fibrous layer in a first curing step, wherein in said first curing step a contact pressure is applied to the resin impregnated fibrous layer, applying a resin coating layer on the at least partially cured resin impregnated fibrous layer, curing the resin of the resin coating layer in a separate second curing step and laminating the resin impregnated fibrous layer on at least one surface of a carrier layer before, during or after the first curing step, or laminating the cured and coated resin impregnated fibrous layer on at least one surface of a carrier layer before, during or after the second curing step.
    • 本发明涉及一种制造耐候层压材料的方法,其包括树脂浸渍的纤维层,优选在载体层上的树脂浸渍的装饰纸层。 本发明还涉及通过本发明的方法获得的层压板,用于制造耐候性层压板的中间层压板以及所述层压板的使用。 该方法包括以下步骤:在第一固化步骤中提供树脂浸渍的纤维层,固化树脂浸渍的纤维层的树脂,其中在所述第一固化步骤中,将接触压力施加到树脂浸渍的纤维层上,施加树脂涂层 在至少部分固化的树脂浸渍的纤维层上层叠,在单独的第二固化步骤中固化树脂涂层的树脂,并且在第一次固化之前,期间或之后将树脂浸渍的纤维层层压在载体层的至少一个表面上 在第二固化步骤之前,期间或之后将固化和涂覆的树脂浸渍的纤维层层压在载体层的至少一个表面上。
