Popis:	The film formation on a micro-scale of latex material is described. Waterborne polymer dispersions dried below their Tg are treated by laser or direct heat treatment by means of a tip (diameter 5 µ m) of a micro thermal analysis apparatus (µ -TA). Both methods give a linewidth, line thickness and dot-sizes in the micron range. The layer thickness decreases during fusion of the particles because of the loss of voids during film formation. Non treated areas can be washed away selectively. Laser treatment gives a more smooth surface than direct thermal treatment with a µ-TA tip. Copyright © 2001 John Wiley & Sons, Ltd.
