A radiation-sensitive resin composition contains: a first polymer including a first structural unit that includes a phenolic hydroxy group, and a second structural unit that includes an acid-labile group; a second polymer including a fluorine atom, a silicon atom, or both, and including a third structural unit that includes an alkali-labile group; a first compound that generates upon an irradiation with a radioactive ray an acid capable of dissociating the acid-labile group within 1 minute under a temperature T.sup.X C. of no less than 80 C. and no greater than 130 C.; and a second compound that generates upon an irradiation with a radioactive ray a carboxylic acid, a sulfonic acid, or both, the carboxylic acid and the sulfonic acid each being not capable of substantially dissociating the acid-labile group within 1 minute under the temperature T.sup.X C.

The present invention relates to latex particles for measurement reagents, said latex particles having a coefficient of variation in particle diameters of 10% or less and an average particle diameter of 250 to 1000 nm. Each of the latex particles contains 20% by weight or more of a compound having a refractive index of 1.60 or more. The depth of a supernatant is 5 mm or less when a liquid dispersion having a solid matter concentration of 1% by weight, which is prepared by dispersing the latex particles in ultrapure water, is placed in a tubular 10-ml measuring cylinder having a body inner diameter of 10.8 mm and is then allowed to leave for 10 days. According to the particles, a measurement of a measurement sample can be performed at a high sensitivity even when the concentration of a substance to be tested in the measurement sample is low.
