Abstract

Translated fromItalian

La presente invenzione riguarda un inchiostro colorato acquoso per penne a sfera che può impedire che la tensione superficiale subisca una diminuzione estremamente elevata, per proteggere lettere scritte dal fenomeno della sbavatura e che è eccellente per ciò che riguarda le caratteristiche di non-essiccamento e che ha proprietà lubrificanti sufficienti a fare ruotare morbidamente una sfera e a fare diminuire l'attrito di una sede di una sfera, per cui le caratteristiche di scrittura possono venire notevolmente migliorate e si possono ottenere caratteristiche di scrittura confortevoli. La composizione di inchiostro colorato acquoso per penne a sfera della presente invenzione è caratterizzata dal fatto di comprendere un pigmento, un disperdente, acqua e un prodotto di addizione di almeno un alcol poliossidrilico con un alchilen-ossido, l'alcol poliossidrilico essendo scelto dal gruppo costituito da poliglicerina, glicerina, trimetilolpropano e una loro miscela.The present invention relates to an aqueous colored ink for ballpoint pens which can prevent the surface tension from undergoing an extremely high decrease, in order to protect written letters from the smudging phenomenon and which is excellent as regards the non-drying characteristics and which has sufficient lubricating properties to smoothly rotate a ball and decrease the friction of a ball seat, so that the writing characteristics can be significantly improved and comfortable writing characteristics can be obtained. The aqueous colored ink composition for ballpoint pens of the present invention is characterized in that it comprises a pigment, a dispersant, water and an addition product of at least one polyhydric alcohol with an alkylene oxide, the polyhydric alcohol being chosen from the group consisting of polyglycerin, glycerin, trimethylolpropane and a mixture thereof.
