Abstract
Tato práce se věnuje studii v oblasti termochromních pigmentů vlivem působení tepla. V teoretické části je provedena rešerše dosavadních poznatků termochromie, dále je uveden přehled z oblasti kolorimetrie, který souvisí s tématem. Experimentální část je zaměřena na studii vlastností termochromního pigmentu během iniciace a relaxace a to z hlediska chování barevné změny v prostoru CIE lab, zároveň je sledována barevná odchylka, maximální barevná odchylka a je ověřena přechodová teplota charakterizující 95% podíl barevné změny, jenž je deklarována výrobcem. Měření bylo provedeno v laboratoři LCAM na katedře textilních materiálů s použitým zařízením - Spektrofotometr Microflash 200d firmy Datacolor International Inc. s geometrií d/8 a měřící aparaturou 20 mm v módu SCI
This thesis is dedicated to thermochromic pigments and its actions under heat. There is performed bibliographic search of current information about thermochromy in theoretical part, furthermore colorimetry overview, which is related to theme as well. Experimental part is orient to study of thermochromic pigment properties during initiation and relaxation phase from color change behavior point of view in CIE lab space and there is also tracked color deviation, maximal color deviation and providing transitional temperature defining 95% share of thermochromic change declaring of producer. The measurement was carried out in LCAM lab of textile material department by using equipment spectrophotometer Mircroflash 200d produced by company Datacolor International Inc. with geometry D/8 and measuring installation 20mm in SCI mode.
