摘要:
The invention relates to a process for utilizing resins useful for imparting dry-strength to paper without substantially increasing the paper's wet-strength wherein the resins comprise non-thermosetting crosslinked polyamidoamine-epihalohydrin resins. The invention also relates to the paper produced containing the resins.

A PSA laminate is provided comprising: a) at least one outer filmic layer (A) comprising at least one filmic polymer; b) at least one adhesive base layer (B) comprising at least one adhesive base polymer; and c) at least one tackifier layer (C) comprising at least one tackifier and at least one polymer; wherein the pressure sensitive adhesive laminate is obtainable by co-extruding the outer filmic layer (A) with the adhesive base layer (B) to produce a non-adhesive laminate and applying the tackifier layer (C) to the adhesive base layer side of the non-adhesive laminate to produce the PSA laminate. Processes for producing the PSA laminate, and articles comprising the PSA laminate are also provided.

摘要:
This invention relates to resins useful for imparting strength to paper, the process of incorporating these resins into paper and the paper produced containing the resins. In particular the invention relates to resins useful for imparting dry-strength and wet-strength to paper under conditions of high sulfite ion concentrations.
