Abstract: PROBLEM TO BE SOLVED: To obtain excellent seal joint strength by a method wherein a substrate is coated with an aqueous dispersed solution containing an ethylene polymer containing respective specific amounts of ethylene and en ethylene unsaturated acid, and a radical polymerized polymer, and the coated substrate is fixed by pressure to a base material at a high temperature. SOLUTION: A substrate is sheets of aluminum, polyvinyl chloride, carbon packaging, etc. An aqueous dispersed solution contains an ethylene polymer, and a radical polymerized polymer. The ethylene polymer contains at least 20wt.% of ethylene, at least 5wt.% of ethylenic unsaturated acid (acrylic acid or the like), and 0-60wt.% monomer different therefrom. The radical polymerized polymer contains 30-100wt.% of principal monomer selected from among C1 -C20 alkyl (meth)acrylate and the like. The aqueous dispersed solution is used as sealing lacquer, and coated on the base material, which is integrated by pressure with a non-coated second base material at 80-250 deg.C temperature.

Abstract: Binders for paper-coating materials permitting even printing, containing a polymer produced by seeding from 1 to 49 wt % of a polymer seed (A) with a glass transition temperature of -80 to +25 DEG C based on esters of acrylic acid or (meth)acrylic acid, and 51 to 99 wt % of ethylenically unsaturated monomers (B), in which there is 10 to 100 wt % of butadiene. The polymer seed (A) is added before or during the polymerisation of the ethylenically unsaturated monomers.

Abstract: Process of sealing comprises pressing together at an elevated temperature two substrates, one of which has been coated with an aqueous dispersion containing a radically polymerised polymer. The dispersion further contains a polymer containing at least 20 wt.% ethylene and at least 5 wt.% ethylenically-unsaturated acid. Also claimed is an aqueous dispersion of a radically polymerised polymer obtained by emulsion polymerisation in the presence of an ethylene polymer. The dispersion further comprises the ethylene polymer.

Abstract: The invention concerns an image-recording sheet for use in thermal-transfer printing, the sheet including an image-recording layer containing a dried latex of a polymer with a minimum film-forming temperature less than or equal to 80 DEG C, the polymer containing 0.4 to 35 % by wt. of at least one self-cross-linking monomer, which is not butadiene, polymerized into it. The invention also concerns the production of this polymer latex, and its use in reproduction processes and in the production of information systems.
