Abstract
Adhesive systems comprised of one or more photoinitiators and one or more adhesives capable of radiation-induced reaction are useful in one-step or multi-step perfect binding of books and other printed articles. The adhesive may be a low viscosity mixture of a monomer and/or polymer which is cross-linkable by UV or stronger electromagnetic radiation.
Claims9
An adhesive system based on at least one of the adhesive components A and optionally B for a one-step or multi-step perfect binding process for book binding, characterized in that it contains at least one photoinitiator and at least one adhesive A) which is capable of a radiation-induced reaction.
An adhesive system as claimed in at least one of the preceding claims, characterized in that the adhesive B is
- a) a hotmelt adhesive based on a polyamide, polyurethane and, more particularly, a high molecular weight copolymer of ethylenically unsaturated monomers, preferably ethylene, with vinyl acetate, acrylic acid and/or methacrylic acid or esters of acrylic acid and/or methacrylic acid, optionally in combination with resins which increase adhesive strength and adhesion based on natural or esterified, dimerized or polymerized colophony resins, polyterpene resins, phenol/styrene resin, aliphatic and/or aromatic hydrocarbon resins and/or with waxes and plasticizers or
- b) a dispersion adhesive based on polyvinyl acetate, polyacrylate, polyvinylidene, polyurethane, polychloroprene and rubber dispersions.
