Abstract
The invention relates to a skin-shaped product comprising an aminoplast-formaldehyde resin mixture and fibrous material and is characterized in that the resin mixture has a viscosity of 25 Pa.s-15.10.sup.3 Pa.s at 120.degree. C. in the skin-shaped product and that the fibrous material in the form of a fleece or a mat has a strength of 0.1 MPa-20 MPa at 20.degree. C.

Skin-shaped product comprising an aminoplast resin mixture which is the reaction product of an amino compound with formaldehyde and further including fibrous material, characterized in that the resin mixture has a viscosity of 25 Pa.s-15.10.sup.3 Pa.s at 120.degree. C. in the skin-shaped product and that the fibrous material in the form of a fleece or a mat has a strength of 0.1 MPa-20 MPa at 20.degree. C.
Process for the production of a skin-shaped product by impregnating fibrous material in the form of a mat or a fleece with an aminoplast resin mixture which is the reaction product of an amino compound with formaldehyde, characterized in that the fibrous material has a tensile strength of more than 0.1 MPa and that the impregnated material is dried, until the aminoplast resin mixture has a viscosity of more than 25 Pa.s.
