    • In a construction of a ski having patterns visible on the bottom, the sole board is made up of a transparent polyethylene resin sheet and a thermoplastic synthetic resin composite sheet sandwiched between the polyethylene resin sheet and the main body of the ski, the patterns being formed on the mating surface of the composite sheet with the polyethylene resin sheet. In manufacturing, a composite film having patterns printed thereon is successively combined with a polyethylene resin sheet by pressure fusion at high temperature. Reduced thickness of the sole board with high masking effect, omission of the wet system painting conventionally used for masking layer formation, and employment of the economically advantageous photogravure printing of the patterns can be expected.
    • 在底部具有图案的滑雪板的构造中,鞋底板由夹在聚乙烯树脂片和滑雪板主体之间的透明聚乙烯树脂片和热塑性合成树脂复合片构成,形成图案 在复合片材与聚乙烯树脂片材的配合表面上。 在制造中,在其上印刷图案的复合膜通过在高温下的压力熔融与聚乙烯树脂片相继地组合。 可以预期,具有高掩蔽效果的底板的厚度减小,省略常规用于掩蔽层形成的湿法涂装,以及使用图案的经济上有利的照相凹版印刷。
