Abstract
A method of using at least one leguminous starch derivative having a predetermined molecular mass in weight and a predetermined sol/gel transition temperature for preparing a composition for laying paper or flat carton. The leguminous starch derivative and laying compositions prepared from the same, in particular with high dried materials are also disclosed.

A method for the preparation of a paper or folding carton coating composition, having a dry matter content greater than 25%, comprising the step of using a leguminous starch derivative having:
- a molecular weight, determined according to test A, at most equal to 0.40.106,
- a sol/gel conversion temperature, determined according to test B, less than 40° C. and
- preferably, an amylose content of less than 60%.
A coating composition for paper or folding carton, wherein said composition:
- has a dry matter content greater than 25%, preferably greater than 30%, still more preferentially comprised between 35 and 75%,
- contains at least one leguminous starch derivative having a molecular weight at the most equal to 0.40.106, preferably at least equal to 0.04.106, more preferentially at least equal to 0.11.106 and in particular comprised between 0.12.106 and 0.40.106, and a sol/gel conversion temperature of less than 40° C., in particular less than 20° C., advantageously less than 10° C.
A leguminous starch derivative having:
- an amylose content of less than 60%,
- a molecular weight, determined according to test A, at the most equal to 0.40.106, and
- a sol/gel conversion temperature, determined according to test B, of less than 40%, preferably less than 30° C.
