ABSTRACT:
A laminated product is provided which has no problems concerning hygienic safety or environment accompanying the use of solvent-based adhesives and which has been tenaciously bonded in a degree equal or superior to that attainable with conventional CR solvent-based adhesives. The laminated product is obtained by bonding a porous organic material and a cloth with an adhesive comprising, as major ingredients, a polychloroprene latex which is obtained by polymerizing 100 parts by mass of chloroprene with more than 0 part by mass and less than 2 parts by mass of an ethylenically unsaturated carboxylic acid in the presence of from 0.5 to 4 parts by mass of a polyvinyl alcohol and then adding a pH adjustor and a radical scavenger and which has a gel content in the chloroprene polymer of from 10 to 60 mass % and a pH of from 6 to 10, a tackifier resin and a metal oxide.
