Abstract
An imprintable sheet of plastic is proposed having a carrier sheet and a layer applied on at least one side for receiving an imprint in which to improve the absorbency, to increase the drying speed of the imprint and to improve the outline sharpness of the imprint the layer receiving the imprint consists of a firm polymer matrix and microporous finely divided solid particles embedded therein. Furthermore, a method is described for producing such an imprintable sheet. The sheet is preferably used for making imprintable self-adhesive or non-self-adhesive labels.
Claims22
In an imprintable sheet of plastic comprising a carrier sheet and a layer applied on at least one side for receiving an imprint with said layer receiving the imprint consisting of a firm polymer matrix and microporous finely divided solid particles embedded therein, the improvement which comprises that said carrier sheet consists of a plastic formed from non-polar monomers and that said layer receiving the imprint forms an integral composite structure with said carrier sheet.
Imprintable label comprising an imprintable sheet of plastic comprising a carrier sheet and a layer applied on at least one side for receiving an imprint with said layer receiving the imprint consisting of a firm polymer matrix and microporous finely divided solid particles embedded therein, wherein said carrier sheet consists of a plastic formed from non-polar monomers and said layer receiving the imprint forms and integral composite structure with said carrier sheet.
In a method for producing an imprintable sheet, wherein a plastic carrier sheet is coated on at least one side to form an absorbent layer for receiving an imprint, the improvement which comprises:
- employing a plastic formed from non-polar monomers as said carrier;
- applying a liquid primer to the side of said carrier sheet to be coated and thereafter, insofar as necessary, dried;
- and
- applying to the side of said carrier sheet thus treated an intimate mixture of microporous finely divided solid particles and at least one binding agent forming a firm polymer matrix by at least one of curing and crosslinking to form a layer and thereafter, insofar as necessary, dried.
