Abstract: This invention relates to a process for the production of a manifold carbonless form having one or more surfaces coated with capsular chromogenic material. The process comprises providing a plurality of continuous webs, at least one web of the plurality of continuous webs being marked with a pattern and at least one non-aqueous, solvent-free coating of the capsular, chromogenic material being applied to at least a portion of at least one continuous web of the plurality of continuous webs. The non-aqueous, solvent-free coating is then set followed by collating of the plurality of continuous webs. The collated, continuous webs are placed in contiguous relationship to one another to create a manifold form. After the continuous webs are placed in collated, contiguous relationship they can be finished by any combination of the steps of combining, partitioning, stacking, packaging and the like. This invention also relates to the manifold form which is the product of the process of this invention.

The non-aqueous, solvent-free coating is then set followed by collating of the plurality of continuous webs. The collated, continuous webs are placed in contiguous relationship to one another to create a manifold form.

Abstract: A process is provided for producing a pressure-sensitive carbonless transfer or record sheet comprising the steps of preparing a liquid chromogenic coating composition by mixing chromogenic material with a liquid radiation curable substance, the chromogenic material comprising either an acidic color developer of the electron donator type or a color precursor of the electron accepting type. The liquid coating composition is coated onto a web or substrate at a coat weight of from about 0.2 pounds to about 8.0 pounds per 3300 square feet of substrate. The coated web is then exposed to radiation for a time sufficient to cure the liquid coating composition to a tack-free film. A novel liquid chromogenic coating composition is produced, the coating composition comprising a chromogenic material and a radiation curable substance.
