Abstract
The present invention relates to a high-concentration starch adhesive prepared by treating a starch slurry at a temperature of 100.degree. C. or above to form a gelatinized solution and suspending an ungelatinized starch in the gelatinized solution. According to the present invention, the viscosity of the starch adhesive can be kept stable over a long period of time; the problems such as warp due to the expansion and contraction, by the absorption of water, of the material to be adhered, can be solved; and the quantity of heat necessitated in the adhesion step can be much reduced.
