| 1. An adhesive composition, comprising:
an aqueous dispersion having a primary part, composed essentially of a gelatinized starch, and a secondary part, essentially
comprising a nongelatinized starch and/or a swollen starch, in which:
the starch of the primary part comprises a starch selected from the group consisting of native and modified legume starches,
native and modified cereal starches and native and modified tuber starches, alone or as a mixture with one another, and
when the starch of the primary part comprises a legume starch, the starch of the secondary part is then selected from the
group consisting of native legume starches, native and modified cereal starches and native and modified tuber starches having
an amylose content of less than 30%, alone or as a mixture with one another, and,
when the starch of the primary part is a native or modified cereal or tuber starch, the starch of the secondary part comprises
at least one native legume starch; and
said legume starches furthermore exhibiting a purity of greater than 90%, colloidal matter and/or fibrous residue contents
of less than 1% (dry/dry), protein contents of less than 1% (dry/dry), and an amylose content of between 30 and 52% (dry/dry).
