Patent CZ-70498-A3 (CZ)
Title: Coating system and its use when producing polyurethane acrylate layers on layered compressed boards
Inventor: HORVATH MICHAEL
IPC: C08G18/38
Filed: 1997-06-19
Abstract: PCT No. PCT/AT97/00138 Sec. 371 Date Feb. 17, 1998 Sec. 102(e) Date Feb. 17, 1998 PCT Filed Jun. 19, 1997 PCT Pub. No. WO97/49746 PCT Pub. Date Dec. 31, 1997A coating system comprised of a resin component, a hardening component and additives. The resin component contains (meth)acrylic double bonds and at least two reactive hydroxyl groups, and the hardening component is comprised of a multifunctional, at least bifunctional isocyanate. The proportions of resin and hardening component in the coating system are stoichiometric. The coating system is suitable for producing laminated sheets with a surface layer of progressively hardening polyurethane acrylate. During a first hardening stage, the free hydroxyl groups of the resin component cross-link with the isocyanate groups of the hardening component, forming a urethane acrylate prepolymer which contains (meth)acrylic double bonds. In the second hardening state, the (meth)acrylic double bonds continue to cross-link, forming the urethane acrylic polymer coating of the sheet surface. The progressive cross-linking reaction may be controlled by altering the reaction parameters, such as pressure, temperature, choice of additives and chemical constitution of the hardening component.

Filed: 1993-10-11
Abstract: PCT No. PCT/SE93/00827 Sec. 371 Date Apr. 10, 1995 Sec. 102(e) Date Apr. 10, 1995 PCT Filed Oct. 11, 1993 PCT Pub. No. WO94/08789 PCT Pub. Date Apr. 28, 1994The present invention relates to a method for mutually bonding at least two moving continuous material webs of material (1,5) to form a laminate (12) which includes at least one puckered material layer. A first and second web (1,5) are advanced at different speeds (V1, V2) to a web bonding means (4) in which the webs are mutually bonded and the resultant laminate (12) is further advanced at the lower speed (V2). Because of the difference in speed between the two webs, that web (1) which moves at the higher speed (V1) at the web bonding moment is puckered while the other web (5) remains smooth. The invention also relates to an arrangement for mutually bonding two material webs (1,5) in accordance with the method, and to an absorbent article (17) which includes a liquid-receiving outer layer (20) which contains at least one puckered, first liquid-permeable layer (21) and at least one smooth, second liquid-permeable layer (22).
