Abstract

The invention is intended to provide a brush which, while maintaining the superiority of animal hairs in paint holding and discharging performance, is free from the stiffening of the roots of bristles 4 and the expansion of the tips thereof even after its use for applying a water paint, and a method for manufacturing of this brush. To achieve the object stated above, the invention uses as its bristles 4 animal hairs whose pH count is adjusted to be neutral or alkaline.

1 . A brush for use in applying a water paint using as bristles ( 4 ) thereof animal hairs whose pH count is kept neutral or alkaline.  
   
   
       2 . The brush for use in applying a water paint according to  claim 1 , wherein 1% to  400 /o of the bristles ( 4 ) are made of a synthetic fiber material.
