ABSTRACT:
Disclosed is a spray pack for use in forming a uniform, stable spray coating, comprising a spray container device and, packed therein, a spraying composition comprising a liquid dispersion medium and, dispersed therein, particulate cellulose having an average degree of polymerization (DP) of not more than 300 and an average particle diameter of not more than 10 μm, wherein the composition has a cellulose content of from 0.1 to 5.0% by weight, and wherein the composition exhibits a maximum viscosity value (ηmax) of 1×103mPa·s or more in the viscosity-shear stress curve obtained, with respect to the composition, using a cone-plate type rotating viscometer in a shear rate region of from 1×10−3s−1to 1×102s−1and at 25° C. A method for forming a uniform, stable spray coating by using the above-mentioned spray pack is also disclosed.
