Title:
METHOD FOR PRODUCING PSEUDO-BONDING PAPER
Document Type and Number:
Japanese Patent JP2002363895
Kind Code:
A
Abstract:

To provide a method for producing for a pseudo-bonding paper having a stable adhesive property and a re-releasability.

In the method for producing the pseudo-bonding paper, a coating solution which includes a non-releasable adhesive base material, fine particle filler and an anionic fluorine surfactant, not bonding in the usual condition but bonding after applying a specific condition and re-releasable after bonding, is applied to a base paper with forming a mono-layered freely falling vertical curtain of the coating solution and continuously running the paper base in a crossing direction of the curtain. The coating solution characteristically manifests ≤40 mN/m of a static surface tension and includes precipitated silica having 1 to 8 μm of the average diameter of the coagulated particle measured by Coulter counter method and ≥200 ml/100 g of linseed oil absorption measured in by JIS K 5101 as the fine particle filler in amount of 20 to 50 wt.% in the coating solution.
