    • The invention relates to a method for producing molded parts, according to which a pigmented coating agent (P) and a radically cross-linkable coating agent (K), which after final cross-linking produces a transparent coating (KE), are applied to a support film, the coating agent (K) is used to produce a dried but not finally cross-linked coating(KT), the coated support film is shaped and back-injected or back-foamed with a liquid plastic material, and the coating (KT) is allowed to cure or post-cure unless it has already done so. The cross-linkable coating agent (K) comprises a radically cross-linkable component (KK) which has H-bridging structure elements in such an amount that 1) a not finally cross-linked coating (MT) produced from the mixture (M) of component (KK) with additives has a ratio of storage modulus G(MT)' to loss modulus G(MT)' of 5 to 200, G(MT)' and G(MT)' being determined at 20 °C by rheological oscillation measurements, and 2) a finally cross-linked coating (ME) produced from the mixture (M) of component (KK) with additives has a storage modulus E(ME)' of 1.0 * 107.0 to 8.0 * 107.0 Pa, whereby E(ME)' is measured by dynamic mechanical thermal analysis in the rubber-elastic range.

    • This invention is a method for the precise placement of indicia with high resolution into the wall of a hollow-form, molded plastisol part. The method includes the steps of preparing a plastisol graphic transfer by casting a base layer of plastisol onto a carrier sheet, printing indicia with pigmented plastisols onto the base layer of plastisol to form a graphic transfer, and over printing the graphic transfer with a body layer of plastisol. After each layer of plastisol is deposited, the layer cured by heating before depositing the next layer and the transfer is heated to cure the final, body layer. The transfer is applied to a selected inside surface of a conventional rotational mold by applying a high-solvent-content adhesive to the mold surface, stripping the plastisol transfer from the carrier sheet and applying it against the adhesive coated mold surface, and pressing the transfer against the adhesive-coated surface of the mold, permitting the applied transfer to dry over a short interval and then continuing with an otherwise conventional rotomolding or slush molding process to obtain a molded hollow form part having the indicia permanently fused into the wall of the part.
