[0046] Adhesive Clarity Test

[0047] Transmittance measurements at visible wavelengths were recorded at 21°C using a spectrophotometer with a wavelength resolution of 2nm at 190 and The transmittance between wavelengths of 820nm is obtained.

[0048] Adhesive caking test

[0049] Each adhesive was assigned a grade based on the amount of caking generated during application to the paper. Using a regular glue stick container with a swivel base, apply the adhesive with moderate hand pressure. Prior to application of the adhesive, the open end of the adhesive coupon was cut off using a razor blade, leaving a flat adhesive surface. Samples showing an appreciable tendency to precipitate and clump the adhesive gel during use were rated as "Poor" and those not prone to settling and clumping were rated as "Good".

[0050] Adhesive Wrinkle Test

[0051] Each adhesive was assigned a wrinkle rating based on the amount of wrinkle caused when two sheets o...

Abstract

An adhesive composition includes 5 to 40 %wt polyvinylpyrrolidone; 3 to 20 %wt alkanoate blend including a first Cn carboxylic acid salt and a second Cm carboxylic acid salt, where n and m are integers in a range from 12 to 22; 20 to 60 %wt of a water-soluble or water-dispersable solid material; 0.5 to 30 wt% of a liquid polyhydric alcohol; and 15 to 60 %wt water. The adhesive composition can be clear and in glue stick form.

Description

Background technique [0001] The present disclosure relates to adhesives comprising alkanoate blends. More specifically, the present disclosure relates to adhesives having properties of long initial tack life, long open time, reduced substrate wrinkling, improved clarity, and / or reduced clumping. [0002] Adhesives are known for bonding decal blanks and include self-supporting solid adhesives as well as flowable liquid adhesives. Aqueous solid binders comprising fatty acid salts provide smooth, even coating and good adhesion on paper, as disclosed in U.S. 3,576,776 and 6,066,689. When using these soap gel based adhesives ("glue sticks"), it is desirable to close the adhesive surface immediately after the adhesive is applied. Due to the rapid loss of low initial adhesive tack due to evaporation of aqueous solvents, rapid bond closure is necessary. Furthermore, despite apparent claims to the contrary, the glue stick has a tendency to cause significant wrinkling of the stamped ...
