    • A layered product which has no problems concerning hygienic safety and environment accompanying the use of solvent-based adhesives and has been tenaciously bonded in a degree equal or superior to that attainable with conventional solvent-based CR adhesives. The layered product is obtained by bonding a porous organic material to a cloth with an adhesive comprising as major ingredients a polychloroprene latex, a tackifier resin, and a metal oxide, the latex being one which is obtained by polymerizing 100 parts by weight of chloroprene with 0 to 2 parts by weight, excluding 0 and 2 parts by weight, of an ethylenic carboxylic acid in the presence of 0.5 to 4 parts by weight of polyvinyl alcohol and then adding a pH adjustor and a radical-trapping agent and which has a gel content in the chloroprene polymer of 10 to 60 wt.% and a pH of 6 to 10.
    • 与使用溶剂型粘合剂相关的卫生安全性和环境方面没有问题的层叠体,并且以与常规的溶剂型CR粘合剂可达到的程度相同或更优异的程度进行了强力粘结。 通过将多孔有机材料粘合到具有包含作为主要成分的主要成分的聚氯丁二烯胶乳,增粘树脂和金属氧化物的粘合剂中获得层压产品,该胶乳是通过将100重量份氯丁二烯与 0至2重量份,不包括0和2重量份的乙烯羧酸,在0.5至4重量份的聚乙烯醇存在下,然后加入pH调节剂和自由基捕获剂,并且其具有凝胶 氯丁二烯聚合物中的含量为10〜60重量%,pH为6〜10。
