Abstract
Provided is low hygroscopic paper obtainable by heat-pressing composite paper comprising a pulp component and/or fiber component and, a liquid crystal polymer filler component made of a liquid crystal polymer exhibiting optical anisotropy in molten state, at a temperature higher than the flow initiation temperature of said liquid crystal polymer by 30° C. or more. The low hygroscopic paper has also excellent machanical strength and heat resistance, and can be used as a substrate paper such as a prepreg particularly useful for electric and electronic circuit boards.
