  • CF sheet for carbonless copy paper and weather resistant tags incorporating same
    Patent number: 5922641
    Abstract: A coated front sheet useful in carbonless copy forms. The sheet has a moisture resistant coating of latex binder, color developer, and pigment in association with a substrate. The coating is formulated to permit formation of a legible image in use in the carbonless copy form, and to minimize the adverse effects of humid weather conditions. The substrate is resistant to degradation by moisture, and may be a moisture resistant polymer or paper impregnated with the moisture resistant coating.

  • Multiple part guest check business form
    Patent number: 5127880
    Abstract: A guest check business form will properly align with and be read by conventional guest check processing machines. The top part of a first, heaviest ply of the guest check has machine readable indicia (e.g. bar code) printed on it. Below the bar code second and third plies are attached to the first ply adjacent their top edges, with the bottom edges of all of the plies substantially in alignment. The adhesive attaching these plies is staggered so that at no point along the form is there adhesive more than one layer thick. The adhesive may be repositionable adhesive, or permanent adhesive. With permanent adhesive it is desirable to provide fine perforations in the second and third plies just below the adhesive attachment of them to the first ply. The first ply is preferably carbonless CF paper, the second ply carbonless CFB, and the third ply carbonless CB.
