Abstract:
The purpose of the present invention is to provide a method for manufacture of an absorbent article, with which it is possible to form a desired coloring pattern upon an absorbent article and to reliably manage the quality of said coloring pattern. Provided is a method for manufacture of an absorbent article, in which: microcapsules, which are provided upon a substrate and in which coloring agents are enclosed, are destroyed in a prescribed pattern, and the coloring agents discharged upon the substrate; and the substrate is coated with a developer, causing the coloring to be expressed in the prescribed pattern via a reaction between the coloring agents and the developer.
