Abstract
PURPOSE:To obtain the title writing utensils which provide smooth discharge of ink and give a writing that will not change with time, by dispersing microcapsules containing a specified reversibly thermochromic composition in an aqueous vehicle to form a water-base ink, and putting this ink into a penholder body. CONSTITUTION:Microcapsules of a diameter of 10mum or less, containing a reversibly thermochromic composition consisting of an electron donating color-forming organic compound, an electron accepting compound, and an organic compound that determines the temperature at which the color changes, are dispersed in an aqueous vehicle composed mainly of a self-emulsifiable dispersion resin having a specific gravity different from said capsules by 0.05 or less, thus giving a water-base ink. This ink is put into a penholder body, to one end of which a pen section having a capillary ink passageway in the axial direction is attached so that the ink is supplied to the pen point of writing utensils by a capillary action through the ink passageway from the rear part of the pen section.
