Abstract
Official abstract text for this publication.
The present invention relates to a colloid composition for forming a foam sheet including: polylactic acid resin particles having an average diameter of 1 μm to 100 μm obtained by pulverizing fibrous particles of a polylactic acid resin.
First claim
Opening claim text (preview).
The invention claimed is: 1. A colloid composition for forming a foam sheet consist essentially: polylactic acid resin particles having an average diameter of 1 μm to 100 μm obtained by pulverizing fibrous particles of a polylactic acid resin, wherein an aspect ratio of the fibrous particles of the polylactic acid resin is 20 to 100. 2. The colloid composition for forming a foam sheet of claim 1 , wherein an average diameter of a longitudinal section of the fibrous particles of the polylactic acid resin is 10 μm to 300 μm. 3. A foam sheet comprising a polylactic acid foam layer formed by foaming the colloid composition for forming a foam sheet of claim 1 . 4. The foam sheet of claim 3 , wherein the polylactic acid resin particles include the polylactic acid resin having a weight average molecular weight of 100,000 to 200,000.
