ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to marker assemblies comprising a support sheet having a surface provided with a porous coating of latent curable material capable of receiving printed indicia, which coating is capable of being subsequently cured to render the indicia substantially indelible.
2. Brief Description of the Background Art
Marker assemblies comprising a support sheet having a surface provided with a porous coating of latent curable material capable of receiving printed indicia are described in our EP-B-0237258, and one commercially successful form thereof comprises a 50-micrometer-thick polyester support sheet having a layer of adhesive on the surface not carrying the porous coating and having a silicone-coated release paper removably adhering to the adhesive. These known assemblies are very successful for use with roll-fed printers, but have unexpectedly proved at times to be unsuitable for sheet-fed printers requiring a supply of sheets in the A3 to A5 size-range, preferably A4. The present invention provides sheets in that size-range using a new construction of marker assembly for improved sheet-fed printing.
SUMMARY OF THE INVENTION
The invention accordingly provides a marker assembly in substantially rectangular form of edge dimensions not greater than A3 sheet size and not less than A5 sheet size, comprising
(i) a support sheet having a surface provided with a porous coating of latent curable material capable of receiving printed indicia, which coating is capable of being subsequently cured to render the indicia substantially indelible, the porous coating preferably being in particulate and/or filamentary form,
(ii) a layer of adhesive on the surface of the support sheet not carrying the porous coating, and
(iii) a plastics release sheet of at least 90 micrometers thickness removably adhered to and covering at least part of the adhesive layer.
