[=1 Gin-based substances are solid at room temperature and are incurable to water, so they have not been used in the field of re-reactive adhesives that use water. The present invention has been made in consideration of the above circumstances.1) A resin-based substance is mixed with a base polymer,
Our goal is to provide a rewetting adhesive that has short synchronization time, excellent initial contact strength, and is especially suitable for machine-applied adhesive binding such as gummed tape. Solving the problems. As a means for doing so, the present invention provides a 1-sl resin having a softening point of 50 to 150'C, which is composed of a Y'1-nornide or fumaride of rosin or L1 gin and a multi-layered resin. solid content of Pase Poly I or its aqueous solution or emulsion 1!,) g,

). In the present invention, it is possible to use 11 resins, wood [1 resins, 1 oils, and 1 resins] in the present invention. , these [1-syn main modification ↑1 products or J, Ru modification ↑1 products for nitric acid or normal acid can be used. Examples of the polyhydric al-1-al which can be used to convert these 1-1 gins into 1-sulfur include glycol, ethylene glycol, and penta-lythritol. In the present invention, -C refers to these 11 compounds or IJ fumarides and polyhydric alcohols.
It is necessary that the sprue has a softening point of 50 to 150°C, more preferably a softening point of 70-11.
A temperature of 0°C is suitable. The sprued product is emulsified in the presence of a 7L-forming agent at lower right C1 under high temperature and high pressure to obtain a 1-fulsion. Next, in the base polymer used in the present invention, it is possible to use a natural or synthetic porin (such as soluble starch, fkis 1 ~ Phosphorus, glue, gelatin, gum arabic, methyl cellulose, carbonyl dimethyl cellulose, polyvinylal-1-al, poly(acrylic)-1 mite, polyacrylic acid or sota salt of I, etc. are used, and these are used in Japan. , or a mixture of one or more of them can be used. Then, the -1-salide emulsion and the base polymer are mixed. The base polymer may be mixed as it is, or it may be mixed with the emulsion of the esterified product in the form of an aqueous solution or emulsion. The combined ratio is 499-80 parts of the base polymer and 1 to 1 of the esterified product as a solid weight ratio.
