COURSE OBJECTIVES: Introduction of Introducing students to binders, the basic component of the coating which is the carrier of the properties of the coating and its synthesis, properties which determine the range or conditions of application. Acquisition of knowledge of the properties of other components of coatings, their influence on the properties of the final product and the methods of manufacture and application. Introduction to the basic concepts of colour and understanding of the relationship between the chemical structure of organic compounds and colour. Introduction to the classification of organic dyes and the basic chemical and application properties of each group. Acquisition of knowledge about the technology of production of selected organic dyes and pigments.

9. classification and role and mechanism of action of certain types of additives in coatings.
10. manufacture and application of coatings. Test methods for coatings and dry films.
11. Basic concepts of color. Empirical correlations between chemical structure of organic compounds and their color. Industrial applicability of colored compounds.
12. Classification and properties of individual groups of organic dyes. Color index.
13. fields of application of organic dyes (textile, non-textile, functional dyes and optical brighteners).
14. technological processes for the preparation of selected organic dyes from different application and chemical classes.
15. Organic pigments: optimization of synthesis and physical processing operations. Influence of crystal structure and particle size on the application properties of pigments.
DEVELOPMENT OF GENERAL AND SPECIFIC COMPETENCIES OF STUDENTS: Understanding the synthesis process of binders. Ability to analyse and relate the influence of structure on properties. Understanding and solving problems related to synthesis, structure and properties. Adoption of the principles of formulation and the influence of individual components on the application properties of coatings and dry film properties. Knowledge of technological production processes, chemical and application properties of organic dyes and pigments.
STUDENT RESPONSIBILITIES: Regular attendance at lectures and laboratory exercises. Absence from the exercise must be compensated. Before taking the exam, the student is required to pass the laboratory test and prepare laboratory reports.
