Abstract

A novel pathological sealing sheet material comprises a sealing sheet material, and the sealing sheet material sequentially comprises a polymer layer composed of acrylics and / or class A acrylics, a pressure-sensitive adhesive layer, a light-transmitting polymer base material and a protective coating from bottom to top. The pathological sealing sheet material is simple in component, good in effect, low in toxicity and novel, is mainly used for sealing sheet after pathological tissue dyeing, has transparency and refractive index similar to those of a glass slide, has rapid interaction with an activating solvent, the sealing sheet material has compatibility with dyeing chemicals used on a sample, and when the sealing sheet material is used on a microscope glass slide, preferably, the sealing sheet material can be exposed to high humidity and high temperature for a long time, but the sealing sheet material cannot be obviously separated from the glass slide, and the dyed pathological sample does not obviously fade.

Description

technical field

[0001] The invention belongs to the field of pathological tissue slice fixation, in particular to a novel pathological sealing material. Background technique

[0002] In life disciplines such as histopathology and microbiology, specimens are often examined using microscopy (eg, light microscopy), a method that requires the specimen to be placed on a glass slide, stained, and then examined using a glass coverslip with adhesive cover sheet. Neutral gums are often used as adhesives in pathological examinations. After the coverslipping is completed, the neutral resin used will take 4-7 days to bond the coverslip and slide well under natural conditions, and it will not be dry after 1-2 months in a ventilated place. The smell of xylene. Until it is completely dry, the pathological slides are not suitable for full digital scanning (easily slip or card) or storage (easily stick to other slides). If a new method of coverslipping could be developed that shortens dr...
