资源简介：
The present invention relates to a process for lignin dissolution in which partial methylolation of lignin is carried out during the step of preparing a solution of lignin in an aqueous medium comprising alkali. The lignin prepared according to the process of the present invention can be used to manufacture lignin-based phenolic resins， which are particularly useful in the manufacture of laminates.
